Abstract
Global navigation satellite system (GNSS) can be employed as a transmitter to composite bistatic synthetic aperture radar (BiSAR). As GNSS signal is quite different from the traditional radar signal, modified spectral analysis (SPECAN) algorithm is proposed and applied in the BiSAR system. The modifications include Doppler centroid compensation, range curve correction and azimuth processing method. The modified SPECAN algorithm solves the imaging problem under the condition of huge range migration, long synthetic aperture time and phase-coded signal. The proposed algorithm is verified by experiment results. Copyright.
